efinet: add structures for PXE messages

When grub2 image is booted from UEFI IPv6 PXE, the DHCPv6 Reply packet
is cached in firmware buffer which can be obtained by PXE Base Code
protocol.  The network interface can be setup through the parameters in
that obtained packet.

Augment existing structures to represent this, and make them agnostic
between ipv4 and ipv6.
